Man arrested in girlfriend's murder

Valrico, Florida -- Deputies have arrested a man for allegedly murdering his girlfriend who was found outside his Valrico home Tuesday afternoon.

Hillsborough Sheriff's deputies say Michael Fields called police about a woman he found dead between his and his neighbor's home in the 2700 block of St. Clouds Oak Drive.

In an interview with detectives, Fields told them the woman was his girlfriend, who was identified as 32-year-old Christina Mahzamani, and that he last saw her around 11 p.m. on March 9 when she left his home in her car.

During their investigation, detectives learned that her car had been found abandoned blocking a driveway in the 500 block of Briar Meadows Drive, about a half-mile away from Fields' home. Mahzamani's car keys and other personal items were found inside.

They then learned that around 8:45 p.m. on March 10, deputies had taken taken a missing persons report from a relative of Mahzamani's who said her kids, ages 13, 9 and 7, told them they had not seen their mother since around 9 p.m. on March 9. The relative went by her home and picked them up.

Detectives arrested Fields at the crime scene for further questioning.

While investigating the crime scene, detectives found a cinder block behind his neighbor's home with blood on it and drag marks and leaves from behind the home to the area where her body was found. They also found a partial shoe impression in the dirt behind his neighbor's home that was consistent with Fields' shoes.

After learning Mahzamani was killed due to blunt force trauma to her head,detectives charged Fields with second degree murder. He is currently being held without bond.

Over the next few days, detectives say they will continue to investigate and try to get a better idea of Mahzamani and Fields' history.
